So true. If I need Vampires I do the first Moonfire Mission solo -1/8... it's easy and very effective.
I soloed the TF a couple of times now. It's not too difficult on Scrappers/Brutes (if you can handle Arrank as an AV solo) and I really like it.
Striga is a Storyarc region I wouldn't skip... the Wedding Band (MOG-toggle) and the Werewolf Whistle (strong pet) are really good temps.
